It is shown by incorporation experiments with ¹³C bond-labeled substrates, followed by analysis by means of ¹³C NMR spectroscopy, that two compounds, 1-deoxy-D-xylulose () and 4-hydroxy-L-threonine (), serve as precursors of pyridoxol (vitamin B₆) () in Escherichia coli. Together, these two compounds account for the entire C₈N skeleton of the vitamin. 1-Deoxy-D-xylulose supplies the intact C₅ unit, C-2,2,3,4,4 of pyridoxol. 4-Hydroxy-L-threonine undergoes decarboxylation in supplying the intact C₃N unit, N-1,C-6,5,5. Both precursors are ultimately derived from glucose. The C₅ unit of pyridoxol that is derived from 1-deoxy-D-xylulose originates by union of a triose phosphate (yielding C-3,4,4) with pyruvic acid (which decarboxylates to yield C-2,2). D-Erythroate () enters the C₃ unit, C-6,5,5, and is therefore an intermediate on the route from glucose into 4-hydroxy-L-threonine.
